• About measurement accuracyWhat an AerTwin measurement can be trusted for, why every figure travels with its qualifier, and what zooming in does and does not change.
• About findings and sign-offsWhat a finding is, what a sign-off binds, what withdraws one, and why numbers and records are never lost.
• About AI proposalsWhere the AI's proposed defects come from, what the AI decides and what it never decides, and how a proposal becomes part of a signed report.
• About working togetherHow several engineers work on one structure at the same time — what each person sees, when changes arrive, and how AerTwin keeps one person from overwriting another.
